Abstract
An anaerobic to aerobic sequence enhances biological degradation of many organic pollutants. Exemplary embodiments provide systems and methods for effective treatment of storm-water runoff pollutants such as hydrocarbons, nitrates, phosphorus, and heavy metals using sediment filtration and adsorption, and biochemical processes under bi-phasic bioretention conditions. By integrating these pollution cleanup pro-usages into a single unit, this apparatus optimizes retention time of the runoff through the system and maximizes removal rates of runoff pollutants, resulting in more reliable and efficient treatment mechanism than previous systems.
